Abstract:	In the Virtual Observatory (VO) era it is critical that the holdings of the ESO Archive are made available to the user community via the usage of VO standards. This requires among other things a good knowledge of the instrumental provenance of the data and the identification of metadata from the otherwise inhomogeneous collection to form a VO layer and a provenance database. The specifications and transmission curves for all optical elements present in the archived observations are being collected for making them available to the astronomical community. As an example, this homogenization work makes possible the mining of the ESO Archive looking for objects observed using specific filters that allow the creation of new outreach images.
